I am sorry I took so long to write you back, Just started college and I am super busy.
I am not quite sure what you are asking, but I think what you mean is the kind of Sunglasses that go darker when you are out in the sun and then go lighter when you enter a building.
And if that is what you are asking the answer is no, they are just normal sunglasses that stay the same darkness all the time.
I hope I answered your question. If I didn't let me know.
